About to start laying and wiring tracks. The sea level route is basically a double main folded dog-bone, and will have one of its two reversing loops hidden along the back wall (it’s the inverted L shape track – coming off the No.5 turnout on the top right side that reconnects on the far left bottom (OR, given the plan is on its side, it’s the right-most inverted L running from the lower right, over the top and that is the left-most track that reconnects on the top left). Note - I've purposely removed stuff from the diagram (and covered another idea for yard tracks with a piece of paper) for ease of viewing it, so please disregard tracks that look like they lead nowhere, etc.
Anyway - was thinking this reversing loop makes an ideal staging or storage track, as it will be hidden and around 28 feet long. But, because it will be hidden, a train parked there might be forgotten and then another train might try to enter that track, causing a collision. I’m assuming there’s an easy way to wire correctly to avoid a train entering that track if it’s already occupied by a parked train. But I can't seem to find anything on this topic in reading through the various books I have on wiring! We'll be running both conventional and command control, but mostly command control. We have DCS now, but will likely add Legacy within the year. Would appreciate any/all help, but I’m not an “electrical guy” so would appreciate “barney” style advice so I can follow it.
Thanks.
Peter
